Which of the following is not true about mass and weight?

55% Answer Correctly

	weight depends on the location where it is measured
	mass depends on the location where it is measured
	weight is the force exerted on an object by gravity
	mass is the amount of matter something has

Solution

Mass is the amount of matter something has while weight is the force exerted on an object's mass by gravity. So, although a person's mass doesn't change when going from the Earth to the Moon, their weight will decrease because the force of the Moon's gravity is much less than that of Earth.

As a cold front moves into an area, the heavier cool air __________ the lighter warm air that it is replacing.

65% Answer Correctly

	mixes with
	pushes above
	pushes under
	cancels out

Solution

A cold front is a warm-cold air boundary with the colder air replacing the warmer. As a cold front moves into an area, the heavier cool air pushes under the lighter warm air that it is replacing. The warm air becomes cooler as it rises and, if the rising air is humid enough, the water vapor it contains will condense into clouds and precipitation may fall.

As part of the carbon cycle, plants release carbon into the atmosphere through which process?

45% Answer Correctly

	sedimentation
	decomposition
	evaporation
	photosynthesis

Solution

The carbon cycle represents the ciruit of carbon through Earth's ecosystem. Carbon dioxide (CO₂) in the atmosphere is absorbed by plants through photosynthesis. Plants then die and release carbon back into the atmosphere during decomposition or are eaten by animals who breathe (respiration) the carbon into the atmosphere they exhale and produce waste which also releases carbon as it decays.
